General' description Described in general terms the machine comprises a series of manipulative devices such as groups of keys which form the operating mechanism for entering the items on the itemized receipt and the totalizers. These keys are arranged upon a rod and each group operates upon cam plates secured to a differentially movable frame to which is secured a segmental rack. The diii'erentia-l movement of the segmental rack imparted by the keys is imparted to the elements of the totalizers as well as the item recording type. In this manner the type carriers are adjusted to a position corresponding to the value of the key depressed;

Totalizer engaging mechanism is provided for the machine, both totalizers being thrown into mesh with the actuating racks when a special key known as the coupler lifting key is depressed a slight amount. Raising of the key coupler by depression of the special key allows other keys to be latched thereto Two totalizers are provided, one which ac-I- cumulates the total' of a seriesof items, known in the art as a subtotalizer, while another totalizer is provided for the total accumulations of all the items additive entered in the machine. vThis totalizer is 'designated as the grand totalizer. When certain of the keys which are known as'transaction keys are depressed the totalizer throwout is actuated so that the grand totalizer is thrown out of co-operative relation with the actuating racks. The keys which actuate the totalizer throwout are the paid out, no sale, and charge keys which transactions do not involve the receipt of cash. The remaining key which usually involves the receipt of money as the received on account?9 key has no control over the totalizer throwout mechanism, both -totali'z'ers being thrown `into cooperative relation with the actuating actuating racks every time the machine is operated irrespective of the nature of the transaction or sale.

. As the items are entered the type carriers will print the amount of each item u on the itemized receipt, the same being fed orward out of the machine an increment during each operation. The printing of items upon the receipt is preceded by an imprint of an electro bearing suitable words in the nature of an advertisement, &c.

When it is desired to take a total a suitable. manipulative device is actuated whereby the printer frame will be rocked forwardly until the platen overlies the subtotalizer accumulating elements where it is actuated to print the total upon the receipt. Restoring movement of the printer frame resets the accumulating elements to zero as an incident to accumulatin'g a subsequent series of items. Simultaneously with the printing of the subtotal upon the itemized receipt the subtotal is also printed upon a record slip from a set of printing elements which operate in unison with the subtotalizer accumulating elements. The last printed subtotal on the record strip is visible to the operator. Operation of the manipulative device for taking a subtotal releases the cash drawer, rings a suitable alarm" and actuates a lock for preventing operation of the keys while takin a subtotal.

At the end of a days usiness or any other desired riod the grand total of the items entered into the machine may be obtained by setting a centralized lock control lever to a certain position. 'This control lever releases certain lids, under one being a manipulative device for taking the grand total. Manipuo lation of this will rock the printing frame forwardly, ina manner similar to taking a subtotal, until the platen overlies the grand totalizer. When in this position the laten is actuated thereby printing the gran total upon a suitable inserted slip. A separate means is also provided for resetting the grand totalizer.

The centralized lock control lever is normally locked and can be adjusted to its various positions only by those who u the key ofthis lock. This control lever controls the manner in which the machine may be operated such as, v open drawer, closed drawer, &c.

The detailed description which is about to follow is divided under suitable headings reference to which will give a detailed description of the various features embodied in the present invention.

n For the purpose of illustration this invention has been shown as applied to a type of machine the general principle of which is disclosed in the U.` S. applications S. N. 263,125 filed November 19, 1918 and S. N.

283,720 filed March 20, 1919 by Frederick L.

Fuller, and the British patents to Frederick L. Fuller Nos. 135,456; 140,363; 157,823; 157,824 and 157,825 for the same invention, but it is to be understood that this invention is not limited to this type of machine but ma with equal facility be applied to other we known forms of accounting machines. The

U. S. applications aforesaid have matured into Patents 1,742,701, January 7, 1930, and 1,729,338, September 24,1929 respectively.

Supporting frames The various parts vof the mechanism are supported by a suitable framework compris-V mg a base casting 21 (Fig. 2) .and side frames 20 (Fig. 4) the latter being connected near their u per rear ends by a castin 24 (Figs. 2 and 5 utilized to support the ta let indicators and mechanism associated therewith.

Further cross connections between the side frame 20 are in the form of a tie bar 23 across,

Keyboard The illustrative machine is provided with 32 keys (Fig. 1) there being three groups of amount keys; one group for entering amounts fromr1 to 9c, one group for amounts ranging from 10 to 90e and the remaining'group for entering denominations from $1.00 to $9.00 inclusive. Four transaction keys are provided for denoting the type of transaction entered into the machine having associated therewith suitable indicators for showing to the bystander the nature of the transaction. The remaining key situated to the extreme left of the keyboard comprises a key known as the coupler lifting key, the purpose and construction of which will be explained hereinafter.

Key coupler f As is usual in a cash registering machine of the t used for illustration, there is p rovide'wkey coupler 36 best shown in Figs. 2, 3, 6, 7, pivotally mounted on a shaft 8 journaled between the side frames 20. Mounted v upon the nose of the key coupler 36 is a series of spring pressed latch plates 9, a latch plate Vbeing provided for each group of keys. Reference to Fig. 2 shows that the pivotal points of the key coupler 36 and keys are displaced with respect to each other so that a circular arc described vby the rear edcgle of the ykey coupler 36 will intersect an arc escribed with the key shaft as a center and passin thru the same point. Advantage is taken o these intersecting arcs for the, purpose of latching or coupling the keys so the depression of any particular ke will result in a depression of all the other eys that have been attached to the coupler. This mechanism is old and well known inthe art and need not be described in detail.

Connected to the key coupler 36 is a lplate 59 (Fig. 2) provided with rack teeth 60 and 61. Fast to a shaft 51 journalled between the side frames is a pinion (not shown) meshing alternately with the rack teeth 60,61. The

result of this is thatwhen the coupler is rocked by the keys the rack teeth of the plate alternately engage the teeth of the pinion fast to the shaft 51 and by 'this means a complete reciprocation of the cou ler effects a complete rotation of the sha Themechanism for eecting rotation of the shaft is also old and is not described in detail.

Coupler Zz'ftz'ngkey A a The key 31 (see Fig. 3) which is preferably located at the extreme left of the keyboard, A besides having certain other functions, hasv for its main purpose to serve as a means whereby the key coupler 36 may be partially '30 raised to what may be termed the coupling home position. VThe rear portion of the key v is provided witha cam surface 52 and co-operating with af face 54 Ona-shoulder of the coupler 36. The surface 53 of the cut in the key provides a stop face which enga es the front edge lof the shoulder of the coup er and stops the motion of the key 'and the key coupler. From this it is evident that when the key 31 is depressed the camede 52 will co-operate with the shoulder to roc the coupler 36 to the position shown in Fig. 3 and in this position the surface 53 of the key will act against the shoulder of the coupler to arrest urther movement ofboth the key and coupler. Any suitable full stroke mechanism, such as that shown in the Fuller application S. N.'263,125 and the British patents previously mentioned may be utilizedto hold the key andthe coupler in this partially elevated position. When the finger is removed lthe weight 57 will assist in allowing the rear end of the key to drop backvtoward its normal leraars the key and raise -a specialindicator 31'- resting .on the rear end-'of the key to the position shown inFig. 1.' v

Y Transaction keys Each of said transaction keysl are [provided with suitable key caps bearing indicia to designate the type of transaction to be registered. Each .transaction key .is loosely 9 mounted upon the key shaft 32, andthe rearward extension thereof lies directly beneath the key coupler-36,l so that when the key cou- Vpler has beenraised andhheld in its coupling position as above described, one of the transaction keys may be partially depressed and latched thereto by means which has been briefly explained heretofore in this application and more fully described and illustrated in the copending application, Serial No. 283,720, filed March 20, 1919 by Frederick L. Fuller and the British patents previously citcd tolwhich reference may be had for further etai s.

It is desirable that an indication be made m5 'of the particular transaction key which hasnspect to the tablet indicators which are appropriate to the amount keys so as to perform` the function of a Bash; i. e., lto conceal the tablet indicators while they are being rased to their uppermost position. When the tablets which have been raised by the op- 12 erated amount keys have been held intheir elevated position, the transaction indicators are lowered and by mechanism appurtenant to the transaction keys are rotated and set an amount to exhibit indicia which indicates the nature of the transaction.

The indicator mechanism is fbrieliy described here as it forms no part of the present invention and for further details of construcis@ tion and operation reference may be had to the British patents previously mentioned.

Amo'amt keg/8 Referring to Fig. 2, it is seen that each of the amount keys l() is guided in its movement by slots 34 formed in the cabinet and lies immediately below the key coupler. Each amount key is provided with a notch .such as 35 engageable by the nose of the key coupler 36 when the keys are de ressed, so that they may be latched to the ey coupler.

vWhen the key coupler 36has been elevated a predetermined distance upon the depression of the coupler liftingkey 31, the nose of the key coupler is elevated so that said nose is slightly above the notch of all undepressed keys. Mounted on the nose of the key coupler are suitable spring-pressed latch plates, as have been described' heretofore,

which spring rearwardly so as to permit said latch plate to slide into the notch 35 when an amount key has been partially depressed, so that a' further movement of the key coupler by any engaged key will result in a complete depression of all partially depressed ke s.

Fach of the numeral keys is provided with an `upwardly extending arm 37 carryn at its extreme upward end a suitable antiriction roller 38 which co-operates with slots formed in a cam plate 41 as will be more fully described hereinafter.

Amount indicators Resting upon the rear ends of the amount keys are indicator stems clearly illustratedl in Fig. 2, so that a complete depression of an amount key will elevate the correspond ing indicator 85 to indicate to the operator and the public the amount of the transaction. Since the indicators 85 are arranged in denominational groups the indicator stems 88 are staggered so that said-stems will lie immediately above the rear end of its corresponding amount key.

The means for retaining the indicators in their elevated position and for releasing them during a previous operation forms no part of the present invention and one form which this mechanism might take is shown in the Fuller application S. N. 263,125 and the British patents previously mentioned, to which reference may be had for a more detailed showing and description.

Differential mechanism similar in construction and rinciple and the description of one will su ce for all.

Loosely mounted upon a shaft 43 journalled between the side frames 20 is a frame 42 (Fig. 2) provided with s aced slots` in which are inserted and secure by any desirable means a series of cam plates 41 one for each key of a particular group. The cam plates 41 are provided with L shaped slots 40, having portions concentric with respect to shaft 43 and other portions extending away from the shaft, and graduated as clearly shown in Fig. 2. The anti-friction rollers 38 co-operate with the respective cam slots and from the foregoing it will be evident that upon a depression of an amount key a differential movement will be imparted to the frame 42. When the frame 42 is actuated differentially the rollers 38 of the undepressed amount keys remaining in the respective bank will play in the' concentric portions of slots 40 provided to permit the u'pward tilting of the cam plates 41 without inerfering with the rollers of the unoperated eys.

It is to be understood that there is a differential frame 42 for each grou of amount keys and one for the transactlon group of keys as well.l

Each dierential frame 42 has secured or connected to it s0 as to be movable therewith a segmental rack 49 (Figs. 3 and 4). Since there are four differential frames there is a similar number of segmental racks, the four racks 49 being shown in Figure 4.

Referring to this figure it will beseen that the totalizer actuating racks 49 are spaced closely together, whereas, reference to Fig. 1 shows that the numeral keys are spaced across substantially theI entire front of the machine. vide suitable transposing mechanism for transmitting the motion from any of the differentially actuated frames to the closely spaced actuating racks shown in Fig. 4, and to this end any suitable bail mechanism for transferring this movement may be conveniently utilized for this purpose.

Means for locking the actuators fn normal posities.

It is desirable that the segment frame and segments attached thereto be locked in normal osition. To this end, one of the plates 41 of) each group is provided with a locking projection 46 which is-adapted to engage with the square face of an upwardly spring urged hook 45. The hook is formed as an upwardly and rearwardly extending pro jection of a bail 44, which 1s common to all the numeral keys of a particular denominational group or order and there is also one rovided for the grou of transaction ke s. ach of the numeral eiys is provided with a projection 48 which 'es over the upper It is therefore necessary to pro edge of the bail 44, so that when a key of a group is depressed, the projection 48 will rock bail 44 downwardly against the action of its sprin 441 and thus disengage the hook iti from t e locking projection 46, so that a particular key may now rock its corresponding plate 41. lt is thus seen that a partial depression of a key is necessary be- .nated as the coupling point, the coupler .likewise is moved through an angular distance corresponding"`t1the movement required by a. numeral or transaction key to unlock its associated segment frame. Hence,

all actuator locks are disabled when the keys are depressed to the coupling point.

. I tem printc'ng wheels A suitable set of printing wheels is provided 4frvthe purpose of positioning type for printing the amount and character of the transactions upon the itemized receipt. Referringto Fi s. 3 and 4, there will be seen a plurality o the type wheels 62. Rigidly attached to each of the type wheels 62 is a pinion meshing with the associated actuatlng rack 49. All the item and transaction y printing type wheels are loosely mounted upon a shaft 200 suitably journalled between the intermediate supporting frames 26. Thus it is evident that when the keys 10 are depressed and their corresponding racks 49,

. thereby given a differential degree of movement the printing wheels 62 will be rotated, correspondingly, so that when suitable impressions means are actuated., said wheels 62 will print characters indicating the amount and nature of the transaction.

lTotalz'zers In the machine disclosed in the accompanying,\ drawings there are shown twov totalizers designated enerally by the letters S and G, the accumulating elements of which are driven by the actuators 49. Referrin partleularly to Figs. 2 and 4, the totalizer 1s deslgned to accumulate the total of quantities to be printed on an issued itemized check..4 This totalizer may he termed a subtotalizer. The totalizer G is designedfto accumulate a grand total of all items additively entered into the machine.

These totalizer-s are pivotally mounted between the side frames 26 just below .the item type carriers 62 and comprise a plurality of totalizer elements 102 the peripheries of Leraars which are provided with suitable printing type so that the totals accumulated thereona manner to be more fully described hereinafter.

The totalizer elements are operable by the segmental racks 49 which set up the item type vcarriers and it is to be noted at this point that although the segmental rack corresponding to the transaction group of keys sets an item type carrier 62 it does not actuate the totalizer elements, the rack teeth being cut away to prevent this as shown in Fig. 8.

ln the particular illustrative embodiment the totalizer S comprises four adding Wheels 102-'but this number may be altered to meet the requirements of a particular registering capacit The totalizer Gr comprises seven ad ing elements, but this number may also be laltered at will-to meet any special requirements.

Thetotalizers S and G are alike in principle and a description of. one totalizer will suiiice for all. The totalizer S is best illustrated in Figs. 8 and 9 of the drawings.

A totalizer frame formed with ears 81 and 82 supports a shaft 201. Each totalizer wheel 102 is rotatable around the shaft 201 and has attached to it a pinion 100, a transfer disc carrying .a tripping tooth 114 (Fi 10) and, except the units wheel, a rate et wheel 101, which is moved one tooth for eiiecting transfers;` Below and parallel to shaft 201 just mentioned is a second shaft 109. This shaft carries the various devices for eiecting transfers which will be explained more fully hereinafter. The frame 80 is further provided with bearings 86 and 87 (Fig. 8) which are adapted to receive studs passing thru the side frames 26 so that the totalizer may be oscillated bodily about the studs to move the totalizer wheels into or out of engagement with the actuating segments.

Transfer mchnc'sm The transfer mechanism employed is of the type known as independently actuated, successive and is operated .upon the return stroke of the keys, at which time the totalizer pinions'lOO are out of mesh with their respective actuators 49. The transfer mechanism is best shown in `Figs. 8-14 inclusive.

As stated before each totalizer wheel 102v has attached to it atene side a transfer disk asuma to the arm'108 is a transfer arm 104 which has pivoted at its rear end a pawl 103 which is provided with a bent over 1u 112.

'The transfer arm 104 is urther provided 5 lwith a stud 105 and a notch, the sides of which are designated by reference characters 127, 128 (Fi 10). The upper enga 'ng end of the trans er pawl 103 carried by t e transfer arm 104 engages the ratchet wheel of the totalizer element of the next higher lorder and normally lies in close proximit to the said ratchet wheel. A spring 106 1s coiled around a spool headed stud 107 secured to the arm 104, one end of the spring being connected to a stud 126 secured to the arm 108 while the other end bears a ainst the lug 112. Normally the spring 106 orces the 1u 112 on the trip pawl 103 against the shel 113 as shown in Fig. 10. Normally the lu 112 is substantially mid-wa between the si es of a notch 128 formed in t e rear end of the Vtransfer arm 104 and allowing the 'transfer pawl 103 to move forwardly at the desired time until the lug 112 contacts with the forward edge.

Each transfer arm 104 whichl carries a transfer pawl 103 is provided with a stud 105 which co-o rates with a slot 129 formed in the forwar end of a transfer operating arm 110 as best seen in Fig. 14.

The transfer operating arms are loosey ly mounted upon Ythe shaft 43 and are provided with rearward extensions 127 carrying oppositely projecting rollers 122 and 123.

Upon the rotation shaft 51 which, as stated before, is given a complete rotation upon each operation of the machine, is secured a series o complementary cams 124 and 125 the peripheries of which are in Contact with their 4,0 associated anti-friction rollers. The pairs of cams are spirally arranged about the shaft 51 so that in a cycle of rotation about the shaft 51 and cams will actuate the transfer arms successively, first the tens transfer arm then the hundreds, etc.

The sequence of operation is illustrated in Figs. 10, 11 and 12 and from the foregoing it will be evident that each time the disc makes a complete revolution rotating in the 50 direction of the arrow shown in Fig. 10 of the drawings, the trip tooth 114 will contact with h the projection 116 and force the arm 108 downwardly against the tension of the spring 106. The result of this movement is that the vertical edge of the shelf 113 will ride along the lug 112 until the said lug clears the shelf 113, whereupon the spring 106 will force the pawl 103 forward sufficiently to bring the upper engagingend of the pawl in line with the n ratchet wheel 101. The position of the parts is now as shown in Fig. 11 and by referring to this figure it will be seen thatthe rearward edge of the notch 128 formed in the arm 104 has limited the forward movement of the 06 pawl103. Y

During the upstroke of the keys the totalizers will be thrown out of mesh and the arm 110 will be oscillated by'its respective cam with the result that the transfer arm 104 is rocked upwardly. As the pawl 103 which is carried thereby begins its upward movement it meshes with a tooth on the correspondin ratchet wheel 101 of the next higher or er and advances the same to effect the necessary transfer. Due to the fact that the transfer arm 104 and the arm 108 are inter-connected by spring 106 the arm 108 will also be raised upwardly until it is arrested by the projection 116 contacting with the peripheryof the disc 115 as clearly shown in Fig. 12. This is an effective means of re venting over-rotation of the ratchet w eel when transfers are to be made.

When the arm 104 and pawl 103 begin their downward movement the pawl 103 will move in a substantial vertical direction over the interfering tooth of the ratchet wheel 101 and upon further downward movement of the transfer arm 110 the lug 112 will move downwardly upon the shelf 113 until it is again in the position shown in Fig. 10. It is to be noted that when the pawl 103 is not set in its transfer position as shown in Fig. 10, it is so far forward of the teeth of the ratchet wheel that the awl 103 will not contact with the teeth of t e ratchet wheel and will therefore, travel upward idly l without actuating the ratchet wheel. It is also evident that in idle operations the lug 112 passes out of Contact with the supporting shelf 113, and on the downward movement of arm 104 the pawl 103 is again restored to its normal cocked position. in the same manner as when a transfer is effected.

In -order to prevent accidental displace#l ment of the totalizer wheels when out of the engagement with the actuating segments 49 a series of pawls 119 is provided. Each pawl 119 is loosely pivoted on the shaft 109 and urged rearwardly by spring 118. Pawi 110 carries a wedge shaped portion 121, which en gages with. an interdental space of the pinion 100, as best shown .in Fig. 10.

Totalzer engaging mechanism As previously 'stated the sub-totalizer S is provided in the present machine for ac cumulations of individual items comprisng a sale and after the total standing thereon has been printed upon the itemized receipt the accumulatingelements are returned to their normal or zero position, as an incident to accumulating another series of items of the successive transaction. The grand totalizer G is provided to accumulate the grand total of all items entered in the machine which involve the receipt of money.v

Certain transactions such as no sale,- charge, and paid out do not involve the receipt of money and it is necessary'of course,

f'jprovidemeans to rock the sub-totaliizer intothat operation of the grand totalizer be prevented which entering these types of transactions and in order that the sub-total of these quantities be printed it is necessa to engagement with the actuatingracks during each operation of the machine irrespective of the nature of the transaction.

This mechanism is best shown in Figs. 6 and 7.

Fixed to the rotation shaft-51 are complep end of vthis-bail is -provided with an` arm 157 which is secured by any desirable means to the forward n From this' it 1sA evident that each time'V the shaft .51 is given a complete rotation the arm 152 and attached bail 158 will be oscillated. Advantageis taken of this oscillating movement to engageand disengage the grand and sub-total-totalizers at v the appropriate times. As stated previously 'the Sub and Grand totalizer elements are mounted upon a shaft 201 d 202 t' l d b u'tabl an respec 'we y Carne y s 1 e a partial rotation in thedirection of the arpivoted frame 'so as to permit them being rocked into mesh with the totalizers. inorder to eect this roekingof the-frames there is. rovided two counter control slides 160l an 1600 the upper end of each being slotted at 163 to embrace the shaft 200 of the detail ried by the inner arm 1581 ofthe bail 158.

The lowerend of slide 1600, is not provided with a slot but is provided with a'hole which receives the stud 159 so'that movement of the arm 1581 is directly communicated to the slide 1600.

The cam plate'l600 is provided with a cam slot 161 which co-operates with the shaft 201 which carries the sub-totalizer accumulating elements while the cam plate 160 is provided with a cam slot 162 en aging the shaft 202 which carries the gran totallzer accumulating elements. It will be evident that whenever the two plates 160 and 1600 are moved i downwardly the two totalizers will be thrown into mesh with the actuators.

It will be remembered that the lower end of the and totalizer controlling slide 160 is not directl connected to the arm 1581 but the stud 159 1s merely received by a slot 1601 formed in the lower end of the slide 160.

- The connection for communicating motion from the arm 1581 to the slide 160 will now be explained. Pivotally mounted upon the stud 159, which is also utilized' as a guide studfor the cam plate 1600 as has been described heretofore, is a second cam plate 165 formed with a cam slot 168. A stud 164 seartr of the arm v152 'at 156.V

which does not involve the receipt of money such as paid out, no sales, and charge keys are depressed the stud will occupy the forward end of the slot, but upon the depression of the recd on acct. key the stud.

will occupy the rearward end of the slot as lllustrated'in' F ig. 7. Likewise in cash transactions, that is, transactions which do not require the depression of a transaction key the stud 164 will also occupy the position shown in Fig. 7.

' From this it is evident that when the parts are in the positions shown in F ig. 7 motion from the arm 1581 has been communicated throughthe stud 159 cam plate 165 andthe stud 161'to the camvplate 160 to rock the grand totali'zerinto engagement 'with the racks simultaneously wit-h the engagement ofl the sub-totalizer.

The sequence of the operation of the parts just described willbe explained, Fig. 7 show- .ing the machine actually'operated, both totalizers being in engagement with the racks.

Upon a depression vof the coupler lifting` key the coupler will be lifted to its coupling point and the rotation shaft 51 will be given row shown in Fig. 7 suii'icientto allow the stud '153 to fall from the highiportion of the cam 151 to the position shown in Fig. 7. The result of this movement will be to rock the vertical arm 152 of the bell crank lever and the horizontal arm 1581 to lower slide 1600 and 160 to throw'. the sub-totalizer and grand totalizer'into mesh. Other keys maynow be attached to the coupler and b depressing aselected amount key the sha t 51 willl be rotated further, but the totalizer pinions will still remain in mesh with the actuating racks to beactuated an amount corresponding to the'value vof the keys depressed. Upon the completion of the downward stroke of the keys the cam plates and 1600 will be rocked upwardly by the mechanism just described and the totalizers will be thrown out of mesh with the actuators and retained in that position during the upward stroke of the keys. Upon the return to normal the keys and cam plates 160 and 1600 will assume the position illustrated in Fig. 2.

Totalz'zer throw'but Upon operation of the transaction keys which do not involve the receiptof moneyz such as the aid ont, no sale and charge fue keys it is desirable to prevent operation of the grand totalizer. This is effected in the pres-` ent machine by providing the cam late 165 with a cam slotv 168 of such a con guration thatit will raise the slide 160 when the cam plate 165 is rotated rearwardly from the position shown in Fig. 7 and this upward movement of the-camplate 160 is utilized -for
